[0025] The quick positioning assembly in the embodiment is a structure for quickly positioning and limiting the backrest framework.

[0026] As shown in Figure 1 、 Figure 2 and Figure 3 , the quick positioning assembly includes two inclined struts 301 fixed to the top of the main support 1, a rear frame 302 fixed between one side of the back of the two inclined struts 301, a front rod 303 fixed between the opposite sides of the two inclined struts 301, a middle rod 304 fixed between the opposite sides of the two inclined struts 301, three intermediate rods 305 fixed between the opposite sides of the middle rod 304 and the front rod 303, two fixed rods 306 fixed to the opposite sides of the first intermediate rod 305 on the left and the first intermediate rod 305 on the right respectively, a double-hand button 307 fixedly installed on the top of the fixed rod 306, a horizontal U-shaped clamp 308 fixedly installed on the front of the intermediate rod 305, two hook support members 309 fixedly installed on the front of the middle rod 304, a pneumatic cylinder 310 fixedly installed on one side of the front of the rear frame 302, a connecting plate 311 fixed to the front of the front rod 303, a vertical U-shaped clamp 316 fixedly installed on one side of the front of the connecting plate 311, and a pressing member arranged between the output shaft of the pneumatic cylinder 310 and the front of the connecting plate 311 and capable of pressing one side of the vertical U-shaped clamp 316.

[0027] The pressing member includes a U-shaped member 312 fixedly installed on the output shaft of the pneumatic cylinder 310, a pressing rod 313 hingedly connected to the inside of the U-shaped member 312 through a pin shaft, a fixed block 314 fixed to the front of the connecting plate 311, and an H-shaped member 315 hingedly connected to the side of the fixed block 314 away from the connecting plate 311 through a pin shaft.

[0028] It should be noted that, as Figure 4As shown, the bottom of the side of the extruding rod 313 close to the connecting plate 311 is bonded with an anti-skid block 317, and the edges of the anti-skid block 317 are arc-shaped. The anti-skid block 317 is a rubber block, and the position of the anti-skid block 317 corresponds to the position of the longitudinal U-shaped clamping piece 316, so that the anti-skid block 317 can cooperate with the longitudinal U-shaped clamping piece 316 to exert positioning pressure on the framework.

[0029] In addition, the front surface of the connecting plate 311 is provided with a movable hole through which the output shaft of the air cylinder 310 penetrates, so that the output shaft of the air cylinder 310 can normally drive the U-shaped piece 312 to move. The inner side of the H-shaped piece 315 away from the connecting plate 311 is hingedly connected to the outer side of the extruding rod 313 through a pin shaft. Specifically, the hinge points of the H-shaped piece 315 and the U-shaped piece 312 are both left-right hinges, so that the extruding rod 313 can normally move, so that the extruding rod 313 can be limited by the H-shaped piece 315 and the fixed block 314 through the cooperation of the pin shaft, and then be pushed by the air cylinder 310, so that the bottom end of the extruding rod 313 can be close to or away from the longitudinal U-shaped clamping piece 316. At the same time, the H-shaped piece 315 adopts a double-pin shaft connection mode, which can reduce the assembly difficulty, so that the whole extruding piece can be conveniently laid and installed.

[0030] At the same time, the bottom of the rear frame 302 is fixedly connected to the top of the main support 1, so that the rear frame 302 can be stably installed on the top of the main support 1. The two-hand button 307 is electrically connected to the air cylinder 310. Specifically, the controller of the air cylinder 310 is electrically connected to the two-hand button 307. The controller of the air cylinder 310 can be a PLC controller. When the two two-hand buttons 307 are pressed and started, the air cylinder 310 can work, which is a protection measure in the industrial processing process. The electrical connection and control mode are both existing disclosed technologies, so they will not be described in detail. The opposite ends of the two fixed rods 306 are respectively fixedly connected to the left and right sides of the second middle rod 305 on the left side, so that the fixed rod 306 can connect the three middle rods 305.

[0031] The working principle of the above embodiment is as follows:

[0032] When the automobile seat backrest framework pre-assembly is carried out, the framework is placed between the top of the two hook supports 309, and the outer sides of the left and right sides of the framework are moved to the inner sides of the two transverse U-shaped clamps 308 for limiting respectively, and finally the outer side of the top of the framework is moved to the inner side of the longitudinal U-shaped clamp 316 for limiting, so that the preliminary limiting work of the framework is completed, the two hands are placed on the two hands buttons 307 respectively, and the two hands buttons 307 are pressed at the same time, so that the circuit is communicated, the air cylinder 310 is started, the U-shaped piece 312 drives the extrusion rod 313 to rotate under the hinged action of the H-shaped piece 315, and the bottom end of the extrusion rod 313 is moved to the side close to the framework, and the anti-slip block 317 and the outer side of the framework abut, so that the limiting work of the framework is completed, and the pre-assembly of the backrest lock and the reel device and the like can be conveniently installed, after the installation is completed, the air cylinder 310 is retracted by pressing the two hands buttons 307 at the same time, according to the above principle, the bottom end of the extrusion rod 313 is driven away from the framework, so that the framework pre-assembled is taken out, and the pre-assembly work of the next framework is facilitated.

[0033] Compared with the prior art, the automobile rear seat backrest framework pre-assembly tool can facilitate the positioning and de-positioning of the automobile rear seat backrest framework through the use of the quick positioning assembly on the main support 1, so that the pre-assembly parts can be conveniently installed on the automobile rear seat backrest framework, the normal operation process is facilitated, the overall structure is very simple, and certain safety protection measures are provided, and the tool can be used after simple learning, is suitable for use in most automobile assembly factories, and has strong practicability, and solves the problem that the framework is not conveniently and simply and stably limited during the pre-assembly process of the automobile rear seat backrest framework.

[0034] The electrical elements appearing in the specification are electrically connected with the master controller and the power supply, and the power supply belongs to the common knowledge in the art. The master controller can be a conventional known device such as a control computer, and can be realized through simple programming by a person skilled in the art, and is an existing disclosed power connection technology, which will not be described herein.
